JAR-CLAMP.

SPECIFICATION forming part of Letters Patent No.353,590, dated November30, 1886. Application filed October 12, 1886. Serial No. 215,984. (Nomodel.)

To all whom it may concern:

Be it known that I, EDWARD H. Bron, of Mendota, in the county of-LaSalle, and in the State of Illinois, have invented certain new anduseful Improvements in Olamps for Jars; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates to certain new and useful improvements in clampsfor fruit-jars; and it consists'in certain peculiarities ofconstruction, to be hereinafter described with reference to theaccompanying drawings, and subsequently claimed.

In the drawings, Figure 1 represents a perspective view of my invention,illustrating the same in operative position; Fig. 2, a plan view, andFig. 3 a vertical transverse section taken on line a: m, Fig. 2.

Referring by letter to the. drawings, A represents a portion of anordinary fruit'jar, that has an annular bead, a, near its upper end toform a seat for a similar bead, b, on the under face of a lid, B; andbetween these beads is usually interposed a packing-ring, c, of rubberor other suitable material. Ordinarily the lid B has its peripheryprovided with recesses d, that serve as seats for the vertical portionsof a wire bail, C, the terminals 6 of the latter being bent in to comeunder the annular bead a on the jar.

I The top of the lid B has a conical depression, f, and that portion ofthe wire bail O that crosses said lid is bent down, as shown at g, tocorrespond with said depression, above named. The top of the lid B isalso provided with an annular groove, h, that receives a ring, D, thelatter having flanges ii, of even height throughout, but which areeccentric in a horizontal plane, and thus present an evenbearing-surface against the bent portion of the bail O; and projectingfrom the ring are thumb-pieces k, for turning the same. The flanges t onthe ring D are diametrically 0pposed to each other, and from the factthat these flanges are eccentric in a horizontal plane the diameter isleast between the points where the ears k join said flanges, and greatest between the points farthest from these ears.

In the operation of my invention, the several parts being in theirrelative arrangement,

the flanges on the ring are brought under the bent bail by a movement ofsaid ring in a direction from right to left, the diameter between theseflanges being gradually shortened as the thumb-pieces approach towardsaid bail,thercby causing thelatter to tighten in proportion'to thisdecreasing diameter. To loosen the lid, the flanged ring is moved in areverse direction to that above described.

It will be noticed that as the diameter between the flanges on the ringdecreases the center or the lowest point on the transverse portion ofthe bail is approached, the bearing between the parts being even andcontinuous.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is I l. The combination, with a jarprovided with a bend, of a lid that rests on the head and has its topprovided with a central depression and annular groove, a ring fittedloosely in said groove and provided with flanges that are of even heightthroughout, but eccentric in a horizontal plane, and thumb-pieces, and abail having the transverse portion thereof bent to correspond with thedepression in the lid, and its vertical portions turned in to come underthe bead on the jar, substantially as and for the purpose set forth.

2. The combination, with a jar provided with a head, of a lid that restson the bead and has recesses in its periphery and a central depressionand annular groove in its top, of a ring loosely fitted in said grooveand provided with flanges that are of even height throughout, buteccentric in a horizontal plane, and thumb-pieces, and a bail having thetransverse portion thereof bent to correspond with the depression in thelid and its vertical port-ions seated in the recesses of said lid andturned-in to come under the bead on the jar, substantially as and forthe purpose set forth.

In testimony that I claim the foregoing I have hereunto set my hand, atMendota, in the county of La Salle and State of Illinois, in thepresence of two witnesses.
